Translation of the original operating instructions
For cyclic speed loads, note that the rotating parts of the device
are designed for maximum one million load cycles. If you have
specific questions, contact ebm-papst for support.
;
Use the device in accordance with its protection type.
Notes on surface quality
The surfaces of the products conform to the generally applicable industrial
standard. The surface quality may vary during the production period.
Strength, dimensional stability and dimensional accuracy are not affected
by this.
The colour pigments of the paints used react perceptibly to UV light over
the course of time. This does not however have any influence on the
technical properties of the products. To prevent the formation of patches
and fading, the product is to be protected against UV radiation. Changes
in colour are not a reason for complaint and are not covered by the
warranty.

Acc. to EN 61000-6-2 (industrial
environment)
EMC interference
emission
Acc. to EN 61000-6-3 (household
environment), except EN 61000-3-2 for
professionally used devices with a total
rated power greater than 1 kW
If several devices are switched in parallel on the mains side so
that the line current of the arrangement is in the range of 16 - 75
A, then this arrangement conforms to IEC 61000-3-12 provided
that the short-circuit power S
sc
at the connection point of the
customer system to the public power system is greater than or
equal to 120 times the rated output of the arrangement.
It is the responsibility of the installation engineer or operator/
owner of the device to ensure, if necessary after consultation
with the network operator, that this device is only connected to
a connection point with a S
sc
value that is greater than or equal
to 120 times the rated output of the arrangement.
4. CONNECTION AND START-UP
4.1 Connecting the mechanical system
CAUTION
Cutting and crushing hazard when removing device
from packaging
→ Carefully remove the device from its packaging, only
touching the housing. Strictly avoid shocks.
→ Wear safety shoes and cut-resistant safety gloves.
CAUTION
Device weighs more than 25 kg! Heavy load when
removing the device!
Risk of physical injury, such as back injuries.
→ Use suitable hoisting equipment to remove the device from
the packaging.
NOTE
Damage to device from vibration
Bearing damage, reduced service life
→ Forces or impermissibly high vibration levels must not be
transmitted to the fan from system components.
→ If the fan is connected to air ducts, it should isolated from
vibrations, for example using compensators or similar
elements.
→ Fasten the fan to the substructure without distorting it.
;
The fan may not be handled in the area around the inlet nozzle during
transport and installation.
There is a risk of damage to the impeller.
;
Check the device for transport damage. Damaged devices must no
longer be installed.
;
Install the undamaged device according to your application.
4.1.1 Installation of RadiPac fan
During installation, transport the RadiPac only with suitable hoisting and
supporting equipment. Use only suitable round slings (see 4.4 Technical
description for product weight). Attach using four round slings wrapped
around the struts. Position the slings as shown in the illustration below.
Ensure that the struts of the support bracket to the left and right of the
motor are vertical. Transport the centrifugal fan in its installed position as
shown in the product drawing. Comply with the notices on the unit. The
maximum acceleration during transport may not exceed 2 g.
